Icon Request: Additional `clock-fading` variants for different expiration states

### Icon name `clock-fading-*` ### Use cases I like the existing `clock-fading` icon, but I'd need it expanded into a small set of variants that represent different stages of expiration instead of just a single "fading" state. Some examples where this would be useful: - Showing how much time is left before a temporary session expires (e.g. session timeout warnings). - indicating different expiration stages for temporary files, caches, invites or download links. - Representing the remaining lifetime of ephemeral content like messages or notifications. - Displaying progressive timeout states in dashboards or monitoring tools without relying only on color. My idea isn't to represent exact percentages, but rather a few distinct visual states (for example: barely faded, half faded, mostly faded and fully faded). Similar to battery or signal icons, these would communicate progression at a glance while keeping a consistent visual language. I'm mostly looking for feedback first. Does this sound like something that would be useful to others or is it just my use-case? --- Another part would be the name-scheming. Here are my ideas: - `clock-fading-low`, `clock-fading-medium`, `clock-fading-high`, `clock-fading-full` - `clock-fading-start`, `clock-fading-middle`, `clock-fading-end`, `clock-faded` Another idea that feels overly descriptive: - `clock-fading-quarter`, `clock-fading-half`, `clock-fading-three-quarters`, `clock-fading-full` ### Design ideas Just rough concepts to better convey what I mean: ### Checklist - [x] I have searched if someone has submitted a similar issue before and there weren't any.
